How to use ActiveRecord aggregate functions with time zones? Posted: 15 Aug 2016 08:31 AM PDT This: User.order(updated_at: :desc).first.created_at returns a value of type ActiveSupport::TimeWithZone. However, this: User.maximum(:updated_at) returns a value of type Time. What is the rational for this? From the docs: The value is returned with the same data type of the column, or nil if there's no row. So what is the proper way of using ActiveRecord aggregate functions with the correct time zone - appending in_time_zone to all results? User.maximum(:updated_at).in_time_zone

Get absolute path of image saved by paperclip in Serializer of rails Posted: 15 Aug 2016 08:25 AM PDT I am saving images using Paperclip, while writing an API I need to get absolute path of image instead of relative path. I have tried dozen of ways but they didn't worked, Actually URI.join or Request.host are not working in serializer. How to get absolute path in serilaizer???

Render Highcharts inside Webix Posted: 15 Aug 2016 08:06 AM PDT I'm rendering Highcharts chart in the Rails app like this and it works fine: #container #report-box = render 'chart' However, I want to show this chart inside Webix scrollview. Now my code looks like this and is not working (no errors, only blank space where the chart should be): #section3{:style => "display:none;"} #container{:height => "800px", :width => "1100px"} #report-box = render 'chart' webix.ui({view:"layout", container:"scroll", rows:[ {view: "scrollview", id: "sections", height: 600, scroll: "y", body:{ { id: "section_3", template: "html->section3", height: 300} } ] }); function scroll(id){ $$("sections").showView("section_"+id); }; I would appreciate any ideas on how to make it work.

Javascript TypeError: variable is undefined Posted: 15 Aug 2016 08:07 AM PDT presently I am working on a Ruby on Rails app, and I am trying to get the below JS to work with the app. The first issue I came across was turbolinks 5.0 was preventing the page from loading the JS on initial load, and I would have to refresh the page in order to load the below JS. I did some googling, and came across this stackoverflow answer, but I can't seem to get the JS to run properly without throwing an error. Any and all help would be greatly appreciated. orders.js console.log('inside orders.js'); $(document).on('turbolinks:load', function() { // Your JS here var payment; jQuery(function() { Stripe.setPublishableKey($('meta[name="stripe-key"]').attr('content')); return payment.setupForm(); }); payment = { setupForm: function() { return $('#new_order').submit(function() { $('input[type=submit]').attr('disabled', true); Stripe.card.createToken($('#new_order'), payment.handleStripeResponse); return false; }); }, handleStripeResponse: function(status, response) { if (status === 200) { // return alert(response.id); $('#new_order').append($('<input type="hidden" name="stripeToken" />').val(response.id)); return $('#new_order')[0].submit(); } else { // return alert(response.error.message); return $('#stripe_error').text(response.error.message).show(); } } }; });

Can't install because I don't have high enough Ruby version, but I do Posted: 15 Aug 2016 08:10 AM PDT I'm trying to add a widget to a dashboard. I've cloned the widget to the correct directory and copied files over to the relevant locations. The final thing to do is run this line: bundle install Everything goes well until I get line : Gem::InstallError: activesupport requires Ruby version >= 2.2.2. Make sure that `gem install activesupport -v '5.0.0.1'` succeeds before bundling. So I've installed that separately: sudo gem install activesupport -v 5.0.0.1 Successfully installed activesupport-5.0.0.1 But when I try to run "bundle install" I get the same error. I even checked by ruby version, and its high enough: ruby -v ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15] What am I doing wrong? Is it choosing to use a lower version of ruby?

How to write validation for enum in rails Posted: 15 Aug 2016 08:38 AM PDT I have an enum in one of my model in my api enum pay_method: { cash: 0, card: 1 } I want to have validation for this enum but i can not do that . I wrote a validation in my model for that but it did not take any effect

How do you merge two jquery posts into one in coffeescript? Posted: 15 Aug 2016 07:53 AM PDT I need to merge these two objects: { swim_lane_id: $(this).closest('ul').data('lane-id') } + $(this).sortable('serialize') into one object that can be sent as the [DATA] in a $.post: $.post($(this).data('update-url'), [DATA] ); $.merge only gives swim_lane_id and an id that is part of the update-url data tag but doesn't give the serialized data from the sortable list. I basically need to be able to pass these through in one post because the update-url data tag routes to a controller action in my Rails application and I need to know which list is being updated for every update action sent to it.

Gem load error when trying to use RinRuby Posted: 15 Aug 2016 08:02 AM PDT I am trying to use the RinRuby gem, but when trying to fire up my rails server I get the following error: in require': There was an error while trying to load the gem 'rinruby'. (Bundler::GemRequireError) Gem Load Error is: No such file or directory - R Backtrace for gem load error is: /Users/reinierverbeek/.rvm/gems/ruby-2.3.0/gems/rinruby-2.0.3/lib/rinruby.rb:164:in `popen' /Users/reinierverbeek/.rvm/gems/ruby-2.3.0/gems/rinruby-2.0.3/lib/rinruby.rb:164:in `initialize' /Users/reinierverbeek/.rvm/gems/ruby-2.3.0/gems/rinruby-2.0.3/lib/rinruby.rb:789:in `new' I have R installed and my .bash-profile file looks like this: PATH="/Library/Frameworks/Python.framework/Versions/3.5/bin:${PATH}" export PATH [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function* export R_HOME="/Library/Frameworks/R.framework/Resources" source ~/.profile I added this bash file, because I also noticed that I am not able to execute R scripts from the CLI using Rscript, but I have to include the whole path "/Library/Frameworks/R.framework/Resources/Rscript" I also tried to edit my path with the following: PATH="/Library/Frameworks/Python.framework/Versions/3.5/bin:${PATH}:/Library/Frameworks/R.framework/Resources/Rscript" but this didn't help

In Rails, how to call an AJAX function and then refresh page when its complete? Posted: 15 Aug 2016 07:37 AM PDT I have a form where I if a user changes the value in one of the drop-down-lists then it needs to change some controls on the form. The way it's currently set up... On drop-down-list change, executes an AJAX call to save the form with new value Before the "update" method executes on my object I mark deleted fields that do not pertain to the new value that was changed In the success function of the AJAX call it executes a location.reload() The current problem is that the reload occurs sometimes before the auto-save method has completed. How can I only reload the page until after the auto-save has fully completed? I don't want to set async: false in the $.ajax because it freezes the entire page before my message to the user is shown telling them to please wait. Please let me know if I've forgotten any code to include below thanks! reports.coffee autoSavePost = (reload) -> console.log('autosave executed'); $.ajax type: 'PUT' url: '/reports/autosave' data: $('#report-form').serialize() dataType: 'script' success: (data) -> if reload setTimeout(location.reload(), 5000); return true error: (xhr, ajaxOptions, thrownError) -> console.log xhr.responseText.substr(0,1500) return false # schedule the next autosave if $('#auto-save').length setTimeout autoSavePost, 60000 else return false return $ -> $(document).on 'change', '#report_position_id', (evt) -> $.blockUI({ message: '<h5>Please wait, "Position Graded" is being changed...</h5>' }); # grey out screen with message until page reloads. autoSavePost(true) return

How to test that JSON-only controller returns 406 Posted: 15 Aug 2016 07:57 AM PDT I have a controller that should only accept application/json or /. I check this in the controller class: ... include ActionController::MimeResponds before_action :require_json def require_json respond_to :json end .... That works pretty well, although there is an UnknownFormat error in the log every time a client uses an invalid accept header. The controller correctly returns HTTP 406 Not acceptable. In the test I write: ... test 'do not accept plain text' do assert_raises ActionController::UnknownFormat do get '/api/v1/ping', headers: {'Accept' => 'text/plain'} end assert_response :not_acceptable ... Then Rake aborts with undefined method error at accept_response since the response is nil. I assume it is not set the normal execution flow aborts at the unknown format exception. But if I do not assert the exception the test will just abort with it. Is it a good idea to throw an exception at every 406? How can I test that I get a 406 returned?

How to rewrite this ActiveRecord qurey to MySQL? Posted: 15 Aug 2016 07:19 AM PDT I have this query from Rails code: cars = Car.where('cars.status = 0 AND cars.new = 0') cars.each do |car| SharedCar.create(car_id: car.id, owner_id: OWNER_ID) end and I would need to run this query directly to MySQL console. How to create a MySQL that would does the same as the ActiveRecord above? EDIT: Focus is obviously on how to combine the first and second query, not on how to load the fist query in MySQL. Thank you.

How to negate a scope? [duplicate] Posted: 15 Aug 2016 06:51 AM PDT This question already has an answer here: Is it possible to negate a scope in Rails 3? 3 answers Below is a scope that I'm using: scope :applying, -> { where(admin_confirmed_at: nil) } Now, I would like to use another scope named confirmed that is exactly opposite to applying: it searches for the records where admin_confirmed_at is not nil. How can I write it using the predefined scope applying? I have tried following: scope :confirmed, -> { !applying } scope :confirmed, -> { not.applying } Eventually, I had to write following: scope :confirmed, -> { where.not(admin_confirmed_at: nil) }

C Stack usage error while using RSRuby with rails Posted: 15 Aug 2016 05:55 AM PDT I try to use RSRuby to execute some R script within my rails project. I created a method inside a module, I call this module from a model and want to store the return value. When I execute this method (from the model > module) using the rails console everything works fine. But when I try to execute this same method within my rails application I get the following error: Error: C stack usage 17589268476924 is too close to the limit Error: C stack usage 17589268476972 is too close to the limit Error: C stack usage 17589268476876 is too close to the limit Fatal error: unable to initialize the JIT This error is not related to the R Script (I tried several very simple scripts, but get the same error regardless of the R code I execute). Does anybody have an idea how I could fix this problem? Apart from this error I found RSRuby the most suitable way to integrate R within Ruby, I had other problems when trying to use RinRuby (a gem load error when starting the rails server, because R could not be found). Executing code from the CLI seems inefficient and returns the output as a string, which is in this case also not feasible.

Display Errors For Nested Form Posted: 15 Aug 2016 04:55 AM PDT I have a nested form in my view; <%= simple_form_for @form, url: url do |f| %> <%= f.input :name %> <%= f.input :description, as: :text %> <%= f.fields_for :account, { :class => 'field' } do |ff| %> <%= ff.collection_radio_buttons(:account_type_id, AccountType.all, :id, :name, selected: ff.object.account_type_id) { |b| radio_button_builder(b) } %> <% end %> Here is my Form object (extending Reform); class ProgrammeForm < ApplicationForm properties :name, :description, validates: {presence: true} property :account do property :account_type_id validates :account_type_id, presence: true end end If I submit the form without filling in any fields, then my <% if @form.errors.any? %> partial will print out three errors; 3 Errors prohibited this from being saved: Name can't be blank Description can't be blank Account account type can't be blank But there is no "error-looking" HTML on my nested form (the account_type stuff). Name and description are fine (as those are fairly straight forward). But; fields_for doesn't put a div wrapper around the radio buttons collection to begin with. There is no other indication that there was an error on this field (like with name and description). How can I address these two points?

Unable to deploy Rails App to DigitalOcean because of unsupported key type Posted: 15 Aug 2016 05:20 AM PDT I have configured the droplet in DO and nginx is up and running successfully. I followed the guide on DO on deploying to server via Capistrano. I can ssh into the server without entering my password. But on running bundle exec cap production deploy:initial I'm getting a very weird error: cap aborted!

How to use subdomain with ActiveAdmin on rails Posted: 15 Aug 2016 04:50 AM PDT I'm trying to access the ActiveAdmin with subdomain "admin.localhost.local:3030" instead of namespace "localhost:3030/admin". I looked it up and I found that I should change the default namespace in "config/initializers/active_admin.rb" to false config.default_namespace = false and I surrounded the routes in "routes.rb" with subdomain constraints constraints :subdomain => "admin" do ActiveAdmin.routes(self) end also, I changed "/etc/hosts" localhost line to be able to test on my machine 127.0.0.1 admin.localhost.local but for some reason, it still doesn't work. I'm trying to access the subdomain by writing admin.localhost.local:3030 and this is what I get from the browser: "The admin.localhost.local page isn't working. admin.localhost.local redirected you too many times."

Rails, align dynamic elements using bootstrap Posted: 15 Aug 2016 05:58 AM PDT I'm trying to make my products display view and align them using bootstrap, like in my model. The problem is that, because elements are create dynamically, I can' t do a big bootstap div for all my elements, in order to set an offset, and if I just set my elem size, they are no aligned at all : I displayed them with black background to see better how each div is positioned. <% @products.each do |product| %> <div class="entry col-xs-4 col-xs-offset-0 col-lg-4 col-lg-offset-0"> <div class="product_img img-responsive"> <%= image_tag(product.image_url)%> </div> <div class="product_description"> <h3><%= product.title %></h3> <%= sanitize(product.description)%> <div class="price_line"> <span class="price"><%=number_to_currency(product.price)%></span> </div> </div> </div> my model is : How can I do please?

factory_girl, transient attribute creates two records Posted: 15 Aug 2016 04:38 AM PDT I have the following factories set up factories/request.rb FactoryGirl.define do factory :request do serves 1 instructions "I want cheap food." allergens "Nothing special" active true transient do requested_by nil suburb nil end after(:create) do |request, factory| if factory.requested_by FactoryGirl.create(:request, customer: factory.requested_by) end if factory.suburb FactoryGirl.create(:request, suburb: factory.suburb) end end end trait :with_customer do customer end end factories/customer.rb FactoryGirl.define do factory :customer do address "321 Sample Street" allergies "Nuts" dietary_info "Nothing" account end trait :with_request do transient do request_count 5 end after(:create) do |request, evaluator| create_list(request, evaluator.request_count, customer: customer) end end trait :with_diet do diet_info factory: :diet_info end trait :with_suburb do suburb end end And I am trying to test that a customer's request is returned with the following Rspec example: it "returns active request assuming there is one" do cus = create(:customer) expect(cus.requests.first).to be_nil re = create(:request, requested_by: cus) expect(cus.requests.first).not_to be_nil # this fails. expected 1, got 2 expect(cus.requests.first.id).to eq 1 expect(re.id).to eq (1) expect(cus.has_active_request?).to be true # this fails as well expect(cus.active_request).to eq(re) end Output expected: #<Request id: 1, customer_id: nil, suburb_id: nil, serves: 1, instructions: "I want cheap food.", all...othing special", active: true, created_at: "2016-08-15 11:33:05", updated_at: "2016-08-15 11:33:05"> got: #<Request id: 2, customer_id: 1, suburb_id: nil, serves: 1, instructions: "I want cheap food.", aller...othing special", active: true, created_at: "2016-08-15 11:33:05", updated_at: "2016-08-15 11:33:05"> (compared using ==) The last expectation fails as well. It seems like two Request objects are created and cus and re refer to different ones, which I don't understand how I managed to create that relationship. This makes testing impossisble because i don't have a reference to the actual request stored in cus.active_request (the model method I am trying to test).

Rails: Refile gem (attachment_image_tag prints wrong URL) Posted: 15 Aug 2016 05:48 AM PDT I'm using refile gem for file uploading and I'm uploading files directly to my amazon s3 public bucket. The files are being uploaded just fine to following URL: https://s3.amazonaws.com/{bucket-name}/store/6309035935359dca1ef549170e7facac9ab3553ad53946cea0bcb8335475 I'm using amazon cloudfront to serve these assets from s3, so the cloudfront url, for the asset given above, is something like this: https://{distribution-name}.cloudfront.net/store/6309035935359dca1ef549170e7facac9ab3553ad53946cea0bcb8335475 The both urls when accessed directly through browser works fine. To display this asset in my app view file I'm using refile gem following helper function: attachment_image_tag(@post, :profile_img, :fill, 350, 350) Now the issue is, this helper method prints a URL something like this: https://{distribution-name}.cloudfront.net/attachments/5845d0a97dc77a57b5b05742a1eb26d629d7cdaa/store/fill/350/350/6309035935359dca1ef549170e7facac9ab3553ad53946cea0bcb8335475/file As this URL is different from above cloudfront URL, it is not displaying the image. How do I force attachment_image_tag function to print the correct cloudfront URL?

I do not know why this is causing an err.

Sphinx (ThinkingSphinx) with no down time? Posted: 15 Aug 2016 04:06 AM PDT I am currently using Sphinx with ThinkingSphinx gem for Rails. I am using delta indices with scheduled indexing via cron. The problem is, for each deploy, I restart the searchd process (configure before starting again) based off the docs. I deploy around 5 times a day and it's not acceptable for me that search goes down every time I do. Is there really a need to restart sphinx every time? Surely, there is a way to achieve no downtime?

Remove white space from params Posted: 15 Aug 2016 04:08 AM PDT I have a piece of code which collects params from a form and reads them into invite as I can see. The problem is one of these parameters is an email which I want to ensure has no trailing whitespace. How could I apply strip to invite and all of the params fed into it? def invite_partner return unless invite = params[:partner] return flash.now[:error] = 'Please select a role' unless role = Role.where(klass: invite[:klass], name: 'Admin').first return flash.now[:alert] = 'Email address already in use' if User.where(email: invite[:email]).first raise 'bugger' unless current_user.is_a?(User) partner_invite = PartnerInviteMailer.invite(current_user.operator, invite[:email], invite[:klass], Portal.portal_for_hostname(host_from_request)) partner_invite.deliver flash.now[:success] = "#{invite[:klass]} invited, email sent to #{invite[:email]}" end
